Abstract

A detergent composition with a superior drying performance is provided comprising a surfactant according to the formula:

wherein n=0-5 and m=10-50;

or formula 2:

R 1 O(AlkO)xM(OAlk)yOR 2
wherein R 1 and R 2 are independently saturated or unsaturated, and possibly hydroxylated, alkyl radicals with 4 to 22 carbon atoms. wherein Alk is an alkyl radical with 2-4 carbon atoms; wherein x and y are independently an integer between 1 and 70; wherein M is an alkyl radical selected from the group CH 2 , CHR 3 , CR 3 R 4 , CH 2 CHR 3 , CHR 3 CHR 4 ; and wherein R 3 and R 4 are independently saturated or unsaturated alkyl radicals with 1 to 18 carbon atoms.

First claim

What is claimed is:

1. A detergent composition comprising a non-ionic surfactant selected from the group consisting of:

wherein
n =0-5 and m =10-50;
and
R 1 O(AlkO)xM(OAlk)yOR 2   (Formula II)

wherein R 1 and R 2 are independently saturated or unsaturated, and possibly hydroxylated, alkyl radicals with 4 to 22 carbon atoms;
wherein Alk is an alkyl radical with 2 to 4 carbon atoms;
wherein x and y are independently an integer between 1 and 70; and
wherein M is an alkyl radical selected from the group consisting of CH 2 , CHR 3 , CR 3 R 4 , CH 2 CHR 3 , CHR 3 CHR 4 , wherein R 3 and R 4 are independently saturated or unsaturated alkyl radicals with 1 to 18 carbon atoms; and
wherein the detergent composition is an automatic dishwashing detergent composition;
wherein the detergent composition comprises a homopolymer of acrylic acid; and
wherein the detergent composition comprises at least two different non-ionic surfactants according to the formulae.

2. The detergent composition according to claim 1 , wherein each of the non-ionic surfactants is present in the composition between 0.5 and 20% by weight.

3. The detergent composition according to claim 1 further comprising an amphoteric polymer.

4. The detergent composition according to claim 3 , wherein the amphoteric polymer comprises a quaternized ammonium acrylamide/acylic acid copolymer.

5. The detergent composition according to claim 3 , wherein the amphoteric polymer comprises:

wherein R 1 is an alkyl group having 10 to 20 carbon atoms;
wherein R 2 and R 3 are each alkyl groups having 1 to 3 carbons; and
wherein R 4 is an alkylene or hydroxyalkylene group having 1 to 4 carbon atoms.

6. The detergent composition according to claim 3 , wherein the amphoteric polymer comprises a diallyl dimethyl ammonium acrylamide/acrylic acid copolymer.

7. The detergent composition according to claim 5 , wherein R 1 of the amphoteric polymer is an alkyl group having 12 to 16 carbon atoms.

8. The detergent composition according to claim 5 , wherein R 1 of the amphoteric polymer is the amido radical

wherein R is an alkyl group having 9 to 19 carbon atoms and a is an integer between 1 and 4.

9. The detergent composition according to claim 5 , wherein R 2 and R 3 have 1 carbon.

10. The detergent composition according to claim 5 , wherein R 4 further has one hydroxyl group.

11. A method of automatic dishwashing comprising:
supplying the composition of claim 1 to an automatic dishwasher; and
operating the automatic dishwasher.
